Today, aim to meet the needs of different applications, many manufacturers choose TVS diodes, such as P4SMA47. As a typical TVS diode, it has many prominent features and advantages. Firstly, P4SMA47 is a 4-wheeled structure, which includes two needles, two Zener diodes and four serials. That way, it can provide a superior protection against the most common transient-voltage-related problems.

P4SMA47 is mainly used in sensitive electronic equipment, such as computers and communications. And it’s capable of meeting a variety of other application requirements in the automotive, commercial and military fields. Besides, it also has abilities to suppress transient voltage, spikes, surges, EMI, EFT and so on. All these features are enabled by its excellent working principle.

Specifically, the P4SMA47 begins to clamp when the input voltage spikes, which can absorb high-energy shock. And this clamping voltage is equal to a TVS diode’s breakdown voltage. Meanwhile, all the four serials are connected in a parallel circuit, and they can’t conduct with each other’s currents. This enables P4SMA47 to reach clamping levels twice as high as that of TVS diodes and trim the peak voltage pulse. Finally, the fast response time helps P4SMA47 quickly handles the transient-voltage-related problems and stabilize the input voltage.

Overall, with its superior protection and excellent working principle, P4SMA47 can effectively suppress transient-voltage-related problems. Therefore, it’s widely used in applications, such as automotive, computers and communications.
